WEATHERPRO OFING MEANS FOR WINDOW-SASHES.

Specification of Letters Patent. Patented Sept. 20, 1921.

Application filed November 21, 1919. Serial No. 839,593.

To all whom it may concern.

Be'it known that I, EDWARD A. Nix, a citizen of the United States, and resident of the city of Montreal, in the Province of Quebec, Dominion of, Canada, have invented certain new and useful Improvements in Weatherproofing Means for Window-Sashes and I hereby declare that the following is a full, clear, and exact description-thereof.

My invention relates to weatherproofing means for slidin window sashes particularly those of rallway cars and has for its object to provide a weatherproofing means which will permit of the withdrawal of the sash from its frame upon removal of the vertical guiding beads or stops. A further object of my invention" is to provide a construction, the parts of which maybe readily applied, .which will not resist the openingand closing of the sash to noticeable'extent and will be substantially concealed from view when the sash is in place.

To this end my invention consists of the construction and arrangement of parts hereinafter described and pointed out in the claims.

For full comprehension however, of my. invention, reference must be had to the accompanying drawings in which similar reference characters and wherein:

Figure 1 is an elevation of a window equipped with my improved weather-proofingrmeans illustrated partly in section;

ig. 2 is a vertical sectional view taken on line 2-2 Fig. 1;

Fig. 3 is a horizontal sectional view taken on line 3--3. Fig. 2; and

Figs. 4 and 5 are detail fragmentary perspective views of the interengaging weather strips.

The frame of a-window such as is commonly used in railwaycar construction is shown in the accompanying drawings and includes side posts 3 and window sill 4, and inside, outside and parting or middle window-stops 5, 5* and 5" respectively, between which the inner and outer sashes 6 and 7 slide, the outside stops being permanently fastened in place as component parts of the car body. r

' My improved weatherproofing means consists of a pair of vertically disposed metal strips 14 and 15, mounted respectively upon the inner faces of the stiles, of sashes 6 and 7. Each of these strips is formed from a indicate the same parts fiat blank one side edge of which is bent upon itself as at 16 in hook form to present a channel adapted to accommodate the bent: back edge of strips on the inner stop and the parting strip respectively, a series of holes 18 being punched out throughout its length adjacent the opposite side edge to accommodate screws 19 for fastening it to the sash.

These strips are adapted to interengage with strips 20 and 21, each of the latter being formed from a wider blank than the strips 14 and 15 and of rectangular cross section presenting two sidesl22 and 23, the edge of the former being bent back upon itself inhook form as .at 24. The sides 23 of these 1ast-mentioned strips extend between the posts 3 and the inside windowstops 5 in one case, and the parting stops 5 in the other case, and are secured to the stops by screws 26, the stops and sashes being rabbeted as at 25 to accommodate their re spective strips.

The hooked side 22 xtends'betweenthe window-stops and the sash with' its hook in interengagement with the hook of the v on the sash. ith the construction and arrangement of parts it will be seen that by taking out the screws 30 which fasten each of the windowstops to the frame, the window-stop with its weather strip may be removed and the sash completely withdrawn without in any way disturbing the weather strips on their supporting members.

. In order to weatherproof the top and the bottom edges of the sash, I attach a folded strip of soft rubber 50, to the top edge of the outside face of the top rail and to the bottom edge of the outside face of the bottom rail of each sash by a relatively heavy metal retainingh plate 51, secured in place byscrews 52, t e sashes being rabbeted for the urpose. r

at I claim is as follows:

1. The combination with a window frame includin side posts, vertical window-stops removab y secured to said posts, and a window sash slidably mounted within the frame and between the stops, of weather-proofing means consisting of a pair of strips one side edge of each of which is bent back upon itself stri . in hook form to present a channel adapted 2. The combination with a window frame including a side post, a wlndow sash, a

window stop and means removably securing the stop to the slde post, of weather-proofing means consisting of a strip secured to the window sash at one side thereof and disposed parallel to the side post, said strip having one sideedge bent back upon itself in hookform, the bent back position extending outwardly away from the side post, a second strip carried by the window stop in position facing the first stri and having its outer side'eoge relatively to the side post bent back upon itself and toward the side post in hookform and interlocking with the hooked portion of the first strip whereby the stop may be removed and replaced without disturbing the position of the strips relatively to their carrying parts and irrespective of the position of the sash.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.
